Measuring and Study the Uranium Concentration in Different Types of Powder Milk

摘要

The uranium concentration and the related radiation hazard in eight types of powder milk were estimated. The uranium concentration in these sample is measured by using the solid- state nuclear track detectors technique. The result show that the maximum uranium concentration was found in(NaNa-NaNa) (2.804 ppm), While the minimum concentration was found in (Guigoz) (1.272 ppm). The result show that the average hazard index of these samples was up to (0.18) , which is the limit being less than 1, and the effective dose average was around (0.677mSv/h ). Key w ords: uranium, effective dose , CR-39.
